Versatile polycarbonate glazing system

Makrolon® Multiwall is an advanced polycarbonate glazing system, offering design freedom for a wide range of commercial, industrial and domestic applications. Domestic applications include pergolas, patios, carports, verandahs, skylights, gazebos, sunrooms or pool covers. Shopping centres, sports complexes, screens, walls or greenhouses are just some of a multitude of commercial and industrial applications for which Makrolon® Multiwall is most commonly used.

Applications

Makrolon® MultiwallThe most versatile polycarbonate glazing systemMakrolon® Multiwall polycarbonate glazing system provides outstanding flexibility in design and advanced heat reflecting and light transmitting performance. An advanced construction of internal walls and chambers gives excellent insulation properties and impact strength. Both sides of the sheet have a co-extruded UV barrier which provides protection from 99.9% of harmful UV radiation, giving superior resistance to outdoor weathering. Made from Makrolon® polycarbonate resin, Makrolon® Multiwall ensures high impact strength, clarity and excellent weather resistance.

The Glazing System Explained The H-Bar system makes handling and installation easy and flexible. The Makrolon® Multiwall sheets simply slot into the H-Bar ready

for fixing to the structure. The glazing bar system allows for thermal expansion and eliminates the need for penetrations through the

sheet, hence the structure is watertight.

Installation Instructions

Important: Sealants – These instructions are designed to prevent leaking and alleviate the requirement for sealants. Sealants, especially silicone, are incompatible with polycarbonate. They will damage the sheet, restrict expansion and contraction, and void the warranty. Use the appropriate Makrolon® Multiwall accessories to complete your project and help protect your structure, without the need for sealants.

Thermal Expansion – When inserting sheet into glazing sections allowance must be made for expansion.

Install sheets with the ribs (flutes) running vertically in the direction of the fall on a roof with a minimum pitch of 5º. Having sufficient fall allows natural weather action to assist in keeping the sheets clean and minimises leaking.

Check recommendation for rafter and purlin spacing in Table 1.

Makrolon® Multiwall sheets can be cut using a sharp knife, hand saw or circular saw with a fine tooth blade suitable for plastics. Sawdust (swarf) should be cleared from the channels with compressed air (or vacuumed) and edges should be free of notches.

If the width of the Makrolon® Multiwall sheets needs to be reduced, trim them as close as possible to the last rib so that optimum clamping action of the glazing bar is ensured.

Peel some of the masking back from the ends of the sheet and apply Breather Tape to the top and Sealing Tape to the bottom ends.

Place the first measured and cut Edge Bar down squarely on the structure (screw side up).

One Piece H-Bar SystemPlace the first measured and cut H-Bar down squarely on the structure (screw side up).

Two Piece H-Bar SystemPlace the first measured and cut base glazing bar on the structure.

The maximum end overhang is 50mm.

One Piece H-Bar SystemSecure the H-Bar to the rafter with a screw (gauge not exceeding 12g) at no greater than 1200mm apart.

Two Piece H-Bar System Fasten the Base Glazing Bars to the rafter with Ripple Tek screws (10 gauge - 16 tpi) at no greater than 500mm apart by fixing through the centre of the base glazing bar and securing it firmly onto the supporting structure. (Ripple Teks for Wood are 30mm long; Ripple Teks for Metal are 21mm in length)

Pull the masking back on the sides of the sheet and place the H-Bar gasket along the whole length of both sides of the sheet.

One Piece H-Bar SystemPlace the next H-Bar on the other side and secure it to the support structure.

Two Piece H-Bar SystemPlace the sheet between the secured glazing bars. Position the first top glazing bar in line with the base. Secure the two bars using a rubber mallet.

It is recommended that the top glazing bar is secured to the rafter with a screw (gauge not exceeding 12g) at no greater than 1200mm apart. Once the next sheet is installed the second and subsequent top glazing bars can be fitted.

Repeat steps 6-8 until all sheets are in position.

When using Aluminium End Caps, place the end gasket along the end of the Multiwall sheet only, stopping at the H-Bar.

Fasten the Aluminium End Cap with a screw to the H-Bar. On the underneath of the Aluminium End Cap drill a small weep hole where it meets the H-Bar.

Use the Edge Bar to finish the assembly on the final rafter.

Safety Recommendations• Never walk on or apply a load or your weight directly to sheeting. Use walking boards along rafters at all times.• Always exercise extreme care when walking on a roof.• Consider all safety requirements when working at heights above 2m.• Use appropriate personal protective equipment (PPE) such as safety footwear, safety glasses and gloves.• All safety practices must comply with the applicable building and/or work cover code(s).

*Required for high wind areas only.33 Special High Wind installation instructions apply. Please refer to Makrolon® Sheet website or

customer service for further details.

Chemical ResistanceMakrolon® Multiwall is affected by: Benzene, petrol, ketones, acetone, phenols, chlorinated and aromatic hydrocarbons, and petroleum based paints, abrasive cleaners and solvents. For more information, contact your local Bayer MaterialScience office.

Handling, Storage and Cleaning• Refer to Safety Recommendations.

• Store sheets on a flat surface (longest length on the bottom) in a shaded area, out of direct sunlight. Stacked sheets stored in the sun will cause heat build-up and possibly distortion, even if covered. Masking film may be difficult to remove. Please also ensure that sheets are protected from atmospheric conditions. If damage occurs in this situation, warranty is void.

• Do not allow moisture to enter the flutes. This may cause sheet discolouration.

• Avoid contact with chemicals, paints, solvents, abrasive cleaners and sealants (especially silicone) as many of these are incompatible with polycarbonate.

• Clean with warm soapy water (mild detergent) and a soft sponge or soft brush. Rinse down thoroughly. Dry with a soft cloth to prevent water marks.

Technical DataUV Protection

Makrolon® Multiwall prevents the transmission of more than 99.9% of harmful UV radiation, measured to standard ISO 9050:2003. Its co-extruded UV barrier protects the sheet

from UV degradation and discoloration. It remains stable under extreme climatic conditions (-40ºC to +120ºC).

Wind LoadMakrolon® Multiwall is suitable for use in high wind load areas and tested to wind code AS/NZS 1170.2:2002. The tests have been conducted according to AS4040.2-1992 conditions (methods

of testing sheet roof and wall cladding, method 2: resistance to wind pressures for non-cyclone regions). Makrolon® Multiwall 700mm wide, 8mm gauge meets 2.5kPa at a span of 1200mm. 980mm wide, 10mm gauge meets 2.12kPa at a span of 1200mm. Please visit our website for further details and specific installation instructions.

Fire PerformanceMakrolon® Multiwall is suitable for use in bushfire prone areas, backed by CSIRO appraisal. It’s also self extinguishing, stopping the spread of flame and has excellent fire resistant properties.

Therefore, this product complies with many fire related tests. They include: AS/NZS 1530.3:1999 for simultaneous determination of ignitability, flame propagation, heat release and smoke release; AS/NZS 3837:1998 for heat and smoke release rates for materials and products using an oxygen consumption calorimeter.

Boundary ConditionsMakrolon® Multiwall is suitable for use when boundary conditions apply, backed by CSIRO appraisal. Conditions apply, contact your nearest Bayer MaterialScience office for further details.
